The Louisiana Department of Transportation and Development is rehabilitating a 50-year-old interstate crossing over the Mississippi River in Madison Parish. 

Built in 1973, the I-20 Mississippi River Bridge connects Madison Parish in Louisiana to Warren County, MS, and provides one of the few interstate crossings over the river.

The $27.5 million project, which began in January 2019, is providing a number of significant repairs including an overlay on the bridge deck, upgraded electrical system, and new roadway lighting components.

The old deck is being resurfaced with new concrete to improve traction and preserve the structural aspects of the bridge flooring. The current electrical circuits are being replaced, in addition to the replacement of nearly 100 roadway lighting fixtures with a modern LED system.

Roadway fiber optics are also being replaced with new cameras and radar, which will integrate the system into Mississippi's IT network.

Additionally, selected bridge bearings are being adapted to provide the ability to reposition the bridge truss upriver as necessary. The steel structural connections at certain locations on the bridge are being modified to improve resilience against all loads and conditions. 

New navigational and aerial beacons are also being installed, along with improvements to the bridge monitoring system and ehancements to the inspection access walkways.

While construction is underway, single lane closures are required, though no lane closures are being conducted in both directions at the same time. The entire project is anticipated to wrap up in early 2021, weather permitting.
